MACHINE FOR FEEDING PAPER TO PRINTNG-PRESSES.

Specification of Letters Patent N o. 11,653, dated September 5, 1854.

To all wko/mt may concern:

Be it known that we, BRADFORD A. RUGG and EZRA H. BENJAMTN, of Oak Hill, in the county of Greene and State of New York,l

have invented/a new and useful Improve nient in Paper-Feeding Machines for Printl ing-Presses.

The nat-ure of our invention consists in desired.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation, reference being had to the annexed drawings; forming a part of this specification, inl

which,

Figure 1, is a side sectional view of ourf i improvements; Fig. 2, a side View; Fig. 3,v portion of a side section of the upper part; l Fig. 4C, section showing the upper part open to receive the paper.

Similar letters refer to like parts.

A, frame of the machine; B, upper portion of same; a, Z), printing-cylinder; a oog-wheels Qn same; a2 b2, springs; c, CZ, c, f, i, 7c, Z, m, n, apron-rollers; o, intermediate wheel; CW, pivot; g, h, aprons; i, ratchet wheel; 2, friction wheel; s, slot; 0, drop board; o', extension rod of same; 7J, sliding bar; g, lifting-piece; s, cam shaft; s s, cams; t, lifting lever; 15, pivot of same; u, paper box'; o, connecting-rod g fw, connectinglever; w, pivot of same; w, ratchet bar; y, rack; e, lifting bar.

It is well known that if we place a number of sheets of paper together in a pile, one above the other, and roll them at one edge, the act of rolling alters the position of the sheets, causing one to overlap the other. We take advantage of this fact in our machine by providing a series of rollers and aprons, by means of which we roll the sheets and cause them to overlap each other as far as required for feeding regularly int-o the printing press.

The upper part of the frame of the machine, B, turns upon a pivot, CZ', and when the paper for printing is to be placedin the. machine, the upper frame, B, and lall the parts thereto attached are thrown up, and the paper placed within the paper-box, u,

and upon the apron, h, as seen in Fig. 4, where the colored lines indicatethe paper. The lower apron, It, moves in the direction of arrows, l, and extends around the rollers,

1 2', ifa-Z, m, n. The upperapron, g, moves in the direction of arrows, 2, and` extends around the rollers, c, al, e, f.

la, is a weighted drop-,roller whichslides up and down, being guided by the slot, k. The object of this drop-roller is to keepthe apron, lz, in constant tension. When there is no paper between, this apron comes in contact with the other apron at, d, as seen in i Figs. 3 and 4.' When the sheets are passing around, d, the weighted roller, le, rises, and

the apron, h, expands so as to accommodateitself to the thickness of the sheets between. The speed of both aprons is the saine. The tension of apron, h, is, also, the same, being always regulated by the weighted roller, lc.

The machine is putin motion by means of the printing-cylinder, b, the teeth of which mesh with those on the wheel, Upon the shaft, s, there are two cams, s', s". The round cam, s, has a connecting-rod, v, one end of which is fastened to the lower part of the lever, w, which has a center at fw. To the upper part of, fw, the ratchet bar, is attached. The lever, fw, being put in motion the ratchet-bar, acts upon the ratchet wheel 2", and gives an alternate movement `to the apron-roller, i', to which the ratchet `is attached. For every revolution of, w, the wheel, z", is advanced one or more cogs. The length of the stroke of the ratchet-bar, is

adjustable, as seen in Fig. 2. The motion of,

z", causes the apron, h, to move in the direction of arrows, l, and with it the other rollers with which the apron is connected, viz, Z. m, n. Upon the opposite end of, z', there is a friet-ion pulley, 2, which imparts motion to pulley c upon the roller, c. Thus the mot-ion of rollers, c and, z', is the same, and, also, the aprons, g, and, L. The sheets to be fed into the press, having been placed upon the lower apron, l1., with their ends resting in the paper-box, u, as seen in Fig. 4, the upper frame, B, with its apron and rollers is shut down, and the machine started. Theapron, h, carries the pile of papers up its incline until the pile comes in contact with apron, g, and roller, d. The apron, 71 now expands in the manner before described, and the sheets bend around the roller, d, and emerge from between the two aprons, upon the top of apron, g, along which they are carried beneath the drop-board, o, toward the printing cylinders.

In bending around the roller, d, the sheets I beyond those beneath, is seized by the springs (a2 52o of the printing into the type.

The apron, g, and, with it, the paper upon its top, is advanced toward the printing cylinder, one notch for every revolution of the wheel, m, or just in time to present a new sheet to the springs, a2, b2, of the printing-cylinder, after the top one has been taken. which the sheets are presented to the printing-cylinders. In feeding sheets into the printing press it is necessary to have some means of freeing the upper sheet while those underneath are detained; otherwise more than one sheet would be drawn into the press at a time. This is accomplished by means of the dropboard, o, which is made to rise and fall alternately with the forward movement of the sheets, permitting the upper sheet to go free, but falling upon t-he latter end of the sheet next below, detaining it and all beneath, while the upper sheet is being drawn into thepress. The proper alternating motion of, o, is obtained by means of the downward extension-rod, 0', which is attached to, o. This extension-rod touches cylinders and drawn upon the top of the lifting-piece, Q. The lifting-piece, g, is raised by the lever,

Fig. 3, showsvthe manner in s having a center, t', the opposite end' being operated by the cam s; the lifting-piece, g, is thus raised, and with it the drop-board, o. The drop-board, o, is easily adjusted to different lengths of paper, by means of the horizontal sliding bar, p, to which lthe drop board is attached. The bar, p, has a rack at one end the teeth of which mesh with a cog-wheel, e, having on thev opposite end of the shaft a hand pulley e. The liftingpiece, g, is elongated at its upper end, in order that the drop-board, 0, shall operate at whatever horizontal position it has been adjusted. At, e, there is a hand-lifting bar for convenience in raising the drop-board by hand whenever desired. Y Y

" Our machine possesses many advantages overany other apparatus for the same pur` pose yet made, being simple,l effective, and cheap. The manner in which the sheets are made to overlap and feed into the press, very closely resembles the operation of feeding by hand. It is immaterial whether the paper is dry or damped in passing through our machine.

Having thus described our invention we 1.

I f 1 2. We claim the combination 0f the dropping-board, 0,operated as described, with the apron, g, in the manner and forthe purn poses substantially as herein set forth.
